To all whom t may concern.'

Beit known that I, HENRY L. ARNOLD, a

vcitizen of the United States, residing` at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Self- Coupling Attachments for Railroad-Cars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specifica-tion.

My invention relates to self-coupling attachments for the ordinal;T d raw-heads of railroadcars.

The object of my invention is to provide a self-coupling attachment which may be readily attached to the ordinary draw-heads of railroad-cars without having to alter the same,and which will couple itself with an attachment like itseif,or with the ordinarylink held in the draw-head of another car,regardless of the existing difference in the height of the same.

A further object of my invention is to provide an inexpensive self-coupling attachment for railroad-cars, which will couple itself with another' like itself, or with the ordinary link, and which may be adjusted to prevent its coupling, if desired.

My invention consists cfa self-coupling attachment for ordinary draw-heads of railroadcars having the combination, with a multiple link adapted to be held in the draw-head, of a vertically-adjristable pin having a series of hooks projecting from one of its sides adapted and arranged to have a vertical movement within the multiple links, whereby a link or series of links passed into the multiple link may be held or relieved at the will of the operator.

In the accompanying drawings, Figure l is a vertical section through the center of two draw-heads and two couplers connected. Fig. 2 is a side view of two of my attachments coupled together and attached to two drawheads, which latter are shown in dotted lines. Fig. 3 is a top view of the same. Fig. fi is a vertical section through the center of one of the multiple links. Fig. 5 is a side view of one ofthe gripping-pins. Fig. G is a top view of the same.

Similarletters referto similar parts throughout the several views.

In the drawings, c represents the multiple link,which is formed, as shown,with a series of short links, cwhich are Ushaped,projecting forward from the npright'sides c2, and a single U-shaped link, b, projecting backward from the sides a2. rEhe inner sides ci' the links c are formed in the center ol' the outer ends with a semicircular depression, c, and the upright sides are formed with circular depressions d. The sides of the links e are parallel and are at right angles with the depressions d. The outer ends of the links a are il-shaped in order to guide them between the link or links of the opposite coupler. The gripping-pin A is formed as shown in Figs. l, 5, and 6, and is provided with a series of projecting hooks, A. On the outer end of these are sernieirculardepressions B, corresponding with the depressions c in the multiple link, the two forming a circular way for the receptionof the safety-pin E, which may be introduced in certain emergencies-such as the breaking of a grippingpin, &c.

In placing my self-coupling attachment on the draw-head of a railroad-car it is only necessary to place the link Z in the draw-head e, after the manner of placing an ordinary link, and then passing the pin f through the link and draw-head, as shown in Fig. l, after which the gripping-pin A is placed in the multiple links, with the small eccentric-lever g (which is attached to the upper left-hand side of the pin by a pivot) in the position shown in Fig. 2.

When it is desired to nncouple one car from another, the lever g is turned to the position shown in dotted lines, Fig. 2, which brings the long side of the eccentric below the center of the pivot and raises the gripping-pin out of the reach of the coupling-link, which may then be withdrawn, the leverg being brought to its normal position, which allows the gripping-pin hooks to project down past the links, and as the opposite coupling-link is pressed against thehooks A the pin A is lifted, and as the links pass beyond the hooks into the IOO the multiple link may be held or relieved at :5 the will of the operator, substantially as described and set forth.

2. In a self-coupling attachment for railroadcars, the combination of the multiple link ce with the Vgripping-pin A, provided with an ec- 2o centric adjusting-lever, g, substantially as de; scribed and set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

HENRY L. ARNOLD.
